Effects of Urbanization on Avian Community of Urban Birds in the Three Gorges Reservoir Area of Fuling

The survey on urban bird community in main towns in the Three Gorges Reservoir Area(Fuling section) was conducted with the method of line transect census during July to August 2009.Effects of urbanization on avian community in the Three Gorges Reservoir Area were discussed.The results showed that 33 species were recorded,belonging to 23 families and 7 orders.Diversity,evenness index and dominant extent of urban birds community were counted for 2.498 9,0.714 7and 0.117 1.Along city grads of common town,center town,center city,urbanization synthetical index was gradually elevatory.Obvious discrimination existed in avian community in different city habitats,as species and community diversity reached tiptop in center town,and evenness index became lower along city grads in opposition to dominant extent.The main urban habitat factors effecting on avian community were foliage height diversity,number of tree species and human disturbance.
